1. The problem statement, all variables and given/known data For 1st order linear ordinary differential equation, how do "unique solution" and "particular solution" differ? 2. Relevant equations if dy/dx = f(x,y) and partial f(x,y) with respect to y are both continuous, then there exists a unique solution within a region R. 3. The attempt at a solution Not really a homework question. I am just curious and sort of confused. The way I understand it is particular solution is a subset of unique solution, is that true?
